Pyrophosphorous acid has the molecular formula:
Pyrophosphorous acid has the molecular formula:
- A. \( H_{3} P O_{3} \)
- B. \( H_{3} P O_{4} \)
- C. \( H_{4} P_{2} O_{5} \)
- D. \( H_{4} P_{2} O_{7} \)
Step-by-step solution
Pyrophosphorous acid is formed by the condensation of two molecules of phosphorous acid (H3PO3) with loss of one water molecule: 2 H3PO3 → H4P2O5 + H2O. Thus, its molecular formula is H4P2O5.
